Thisv invention relatesftdA afm-improved power t transmission mechanisinand has for one `of its principal objects the: provisiono means ,whereby reciprocatory motion-may be efficiently land economically` converted: intoirotaryl, moti0n;:j0rr n y Y Y y i iiy Wheels y2l) which insures an easily and,y univiceversa.

One of theimportanntobiects ofthis `invention is to. provide a: mechanism for powertransmissionvwhichshaligbe simple of construction, readily operated, not likely to get o utof order, and which.. canfhe used inyalmostany position Wherel power t'ransxnissic-inv is employed..n

A. still .further important obiect, of .the invention 'resides'v in the` provisionof.- anmeans ,for transmitting power; which-can be...madeof ,vari-- ous sizes arranging vfromjavery small @unit 'totone vofenormous size fand vwithout'' departing fromgthe vgeneral principles and Kmethodsv of: operatiomset `forth.

Another and'stiilpimportantiobiect of the-inw- 'vention .resides inthe provi-sion of g apower mechanism which` may haves'ai'seifcontainedsourceof power whereby this power may bev-transmitted in either increasedV orf reduced;speeds;v to meet various requirements;

other and further important objects, anche" Vinvention vvillbey apparent. from 'the l-dis'zlosures in the accompanying? drawings and following specification.V
